Troubleshooting Hints

PERFORM BEFORE BEGINNING SYSTEM DIAGNOSIS
1. Check GAGES Fuse by visual inspection.
2. Check that G202 is clean and tight.
3. Check brake fluid.
4. If brake fluid is low and the "BRAKE" Indicator does not light, check the Brake Fluid Level Switch.
5. If equipped with Antilock Brakes and "BRAKE" Indicator is lit, check for trouble codes. Refer to Antilock Brake System. Antilock Brakes / Traction Control Systems
6. If equipped with Daytime Running Lights (DRL), and the "BRAKE" Indicator does not light with the Park Brake set, check CKT 33, CKT 1134 and Park Brake Switch for an open or short to B+. If OK, replace the DRL Module.
7. If the "BRAKE" Indicator does not light at all, check:
- The "BRAKE" Indicator bulb for an open.
- The Instrument Cluster printed circuit for an open.
- The TAN/WHT (33) wire for an open.
^ Check for a broken (or partially broken) wire inside of the insulation which could cause system malfunction but prove "GOOD" in a continuity/voltage check with a system disconnected. These circuits may be intermittent or resistive when loaded, and if possible, should be checked by monitoring for a voltage drop with the system operational (under load).
^ Check for proper installation of aftermarket electronic equipment which may affect the integrity of other systems (Refer to General Troubleshooting Procedure). Diagnostic Aids
^ Refer to System Diagnosis. System Diagnosis
